Officer Kevin Coomey, one of the first responding officers, found Cousins sitting on the ground outside of the Electrical Engineering building with his hands behind his head. According to court documents, Cousins had blood on his hands and clothes.

A magistrate entered a not guilty plea for Cousins Thursday. Cousins has been charged with murder. His defense attorney is former Allen County Prosecutor, Robert Gevers.

A shooting that killed one man was reported on the Purdue University campus Tuesday afternoon.

Police believe 23-year-old Cody Cousins, who has a postal address in Warsaw, went into a classroom in the Electrical Engineering building, shot Andrew Boldt, a 21-year-old teaching assistant, and then left the building. About 20 to 25 officers were on the scene "within minutes" according to law enforcement officials.

After police cleared the building, they continued to search the area and shortly before 2 p.m. it was announced that there was no ongoing threat to campus and that normal operations could resume.

Cousins was booked into the Tippecanoe County Jail. Police say that he has not been cooperative.

The Purdue Exponent reports that the shooting happened during a lab session taught by Prof. David Meyer for a "micro-processor and system design" class.

According to the IPFW Facebook page, an emergency alert went out from Purdue about an active shooter on the West Lafayette campus and some IPFW students received the alert and mistakenly thought the shooting was on the Fort Wayne campus.

Purdue president Mitch Daniels was in Colombia on a business trip at the time of the shooting. Daniels cut short his trip, and returned to West Lafayette on Wednesday.

"It's stunning," Daniels says. "There's something about it happening in a place of learning on a college campus. Obviously, when it happens to a young person--a brilliant young person--these things, I think, hit us harder."

Students held a candlelight vigil Tuesday night to honor Boldt and to come together as a campus. The "#BoilerStrong" hashtag was widespread among social media in an effort to show solidarity.

The Purdue men's basketball team was at Northwestern University for a Tuesday night game. Welsh-Ryan Arena held a moment of silence before the game; and members of the Wildside student section wore "Stand With Purdue" in body paint on their chests.

Additionally, classes were canceled Wednesday. Purdue University officials announced Wednesday that the Electrical Engineering Building is expected to open noon Thursday.

As the Purdue community walks on egg shells, the Purdue University Police Department responded to reports of shots fired at Purdue Village, 139 Airport Rd., around 8 p.m.

Purdue officials later said the reports of gunshots were unfounded, and the scene was cleared.
